TROUGI-I.

Specification of Letters Patent.

Patented m. 10, 1918.

Application filed June-22, 1916, Serial No. 105,196. Renewed November 4, 1918. Serial No. 261,171.

lb all whom it'may concern:

type of troughs used as*feed troughs-and into which swill, milk, water and other liquids and semi-liquids are poured. It is therefore essential that the trough be Watertight.

Troughs having seams are usuallysealed with solder. Frequently a portion of the seam is missed, and often the seams will meet with an accident which will cause them to spring apart and thus destroy the efficiency of the trough.. Moreoven-in manufacturing seamed troughs there is a large loss of material, due to cutting off and rounding corners, etc. The seams are at the corners, and these being the most exposed portions are consequently the most liable to become dented or otherwise injured. Dirt and filth collect about and in the seams, rendering the trough unsanitary and difficult to clean.

With a view of overcoming these objec-' :factured with but a minimum waste of stock; which is absolutely water-tight; which may be thoroughly cleansed with ease and facility; which will not injure an animal leaning or rubbing against it; and which may be nested for shipment.

In the accompanying drawing, which illustrates my invention: Figure 1 is a plan view of a blank from which the cross-pieces are formed; Fig. 2, a perspective thereof,

showing it when completed; Fig. 3, a plan view of one end portionof the blank from ,which the trough-body or trough proper blank from which the trough-body or trough proper isformed, and it comprises a body portion3 at each corner of which is a projection hand at each end ,of the body portion is a pro-j'ection'b the edges 6 of which taper toward its end 7.

'To' shapethe trough-body the part 3 is bent or curvedlongitudinally to form the bottom and sides, "the edges of the latter and also of the projections 4 being bent on the dot'ted lines a to form flanges 8and the v edges 1O refl'exed on the dotted lines I) to I provide a smooth edge 11 against which the hogs may lean or rub without injury to either themselves or the flange. The end pieces 5 are bent on the dotted line 0 to form the trough ends 9. As this operation is being, performed, that portion of the. metal which lies between the lines 0 and 45 will crimp or bulge. These bulged portions I then squeeze together on the lines ee and then ifold them over against the trough body, whereby they act as reinforces 12 for the angular corner portions thereof. It will be noted that I have shown both sides and both ends as tapered, whereby the troughs may be nested for shipment. While this feature is much to be preferred, the troughs may be otherwise shaped if desired. 1414 designate cross-pieces or end flanges, each formed from a blank 15 which is refleXed on the line 7 to provide a smooth, projecting edge 16, and which is bent on the line 9 to form a lip 17 which overhangs an end 9. Each cross-piece is fixed by rivets 18 to the projections 4 at the respective ends of the trough. The ends 9, being plane and smooth, without corrugations or @utings, will nest more effectively than when formed in any other manner, and they are more sanitary, for they are not so liable to catch dirt and they may be more easily cleansed.

19 indicates supporting legs. Having thus described my invention claim as new the following, to-witz.

15A tro'ughmade from a single piece of metal and comprising a body substantially arcuate in cross-section and having divergent ends, portions of the metal at each corner being squeezed together and overlying an adjacent portion of the body, the edges I gent ends, portions of the metal at each corner being squeezed together and overlying an adjacent portion of the body, the edges of the body bent outwardly to lie each in a horizontal plane, the ends being plane and there being no projections on the interior of the trough.

3. A trough made from a single piece of sheet metal and comprising a body substantially arcuate in cross-section and having plane, divergent ends, portions of the metal at each corner being squeezed together and folded to overlie an adjacent portion of the body, the lateral edges of the body being bent outwardly to lie each in a horizontal plane, a plurality of said troughs, including the squeezed together portions, adapted to be nested.

4. A trough formed from a single piece of sheet metal and comprising a body portion substantially arcuate in cross-section and having plane, divergent ends, portions of the metal being squeezed together and folded to overlie an adjacent portion of the body, a plurality of said troughs, including the squeezed together portions capable of being nested.

5. A trough constructed of a single sheet of fiat metal capable of being doubled upon itself, and comprising a body arcuate in cross-section and divergent ends, portions of the metal adjacent each meeting place of a side and end being squeezed together and bent to overlie an adjacent portion of the body, the edges of the body being bent outwardly to form flanges.

Signed at Bushnell, in the county of Me- Donough and State of Illinois, this 14th day of June, 1916.
